NOT A BUILD GUIDE Latest test for reduced projectile speed rolling magma, on a hierophant utilizing an arcanist brand for reduced chain Build actually does feel nice, especially after fulling ramping. it is capable of melting bosses, but as I took a break from poe and haven't put any investment into the build, it suffers tremendously from lack of defenses.
You could potentially forgo all defenses and just slam as much cast speed as possible in order to kill before being killed. Or you can invest in more mana and higher end gear to get it to a "playable" state. Switched in Rigwald's Quills instead of craghead because it comes with a max 50% increased projectile damage, which can be pushed to 175 with a perfect widowhail. Loses the potential stun defense, but gains a massive damage boost.
Again, not a real build, and I do not suggest copying my current pob directly. If I'm being honest I'm a little burnt out on poe and don't have the currency to invest into this experiment for now. I will come back to the concept when I feel the itch again
